Question

At a year old the ice maker won't work. For a while it would make a little ice and quite again. Now it does nothing. We have changed the filter, taken it out to "thaw" and still nothing. Is there anything else we can do? The water works on the front of the door and has good flow. We can put ice into the bucket and it will come out of the door. It just won't make ice! HELP AND THANKS!
